When you say that these are precedents, you are mistaken. These are common rules of conduct in every chat worldwide and on FlyOrDie as well!
Accidental writing in capital letters does not bring about a punishment. But we ask the player to put down their caps, because writing in uppercase letter is shouting.
And be informed that only moderators, not assistants, can issue temporary banishments. Therefore you can see that the moderation fully supports catsgirl's decisions.
In my humble opinion, it would be wise to please accept the authority of moderators and assistants in the future so that everyone can have an enjoyable time here and no one has to go through this amount of stress.
